Followed the instructions to a t. Did everything it said to change it. Have everthing downloaded. I followed the set up (no errors) and when it was done, checked the software version and said 4.2. Even tried 4.3 and same thing. 4.2. at&t must have mine locked up tighter than fort knox.

Thank you all for giving me the courage to upgrade my 8700g (Maxis Malaysia) from OS 4.1 to 4.5 (used the one from Dialog Sri Lanka). This was a big leap for me. Everything seems ok for now - fingers crossed.

4.5.0.52 for the 8300

I just posted a thread under the 8300 forum and hayden also put it up here!!! So happy this finally came out for us 8300 users. I'm not at a computer where I can do anything with it right now, so if anyone else installs it, please let us know how it goes!!!

Has anyone ran into problems with their 4.5 O/S not being able to run Telenav after install. I just called ATT and the tech support guy said that it may possibly be a conflict with O/S and Telenav software.
